Dynamics Market Sizing

For along time I've enjoyed many of your posts. Believe it or
not, I find the "discussions" to be very entertaining (maybe
that says too much about me :)).

Here’s my dilemma…

My company is about to develop a new product (platform)
initiative (we offer an add-on document imaging solution)
focused on the ERP space. To begin, our focus will be 100% on
Dynamics (GP, NAV, AX etc.). In an effort to justify investment,
I’m hoping that some of you could provide insight as to the size
of the market. Specifically the client install base. As you
know, MS generally does not make theses number public. However,
over time, there are many “whisper” numbers. The web has
provided some insight --- but the numbers vary too much to
support a reasonable level of confidence.

Can any one tell me/or direct to what the existing install base
is for the following MS ERP offerings (my current estimates are
in brackets):

Thanks for your feedback. We actually already have a solution for GP & NAV (KwikTag). Originally, I was inquiring about market sizing to justify our next generation app and to help determine adjustments to our business model.

If you like, I’d be happy to address your KwikTag questions personally (hopefully saving you the sales pitch). If and when you are ready, I would put you in touch with the appropriate contact.

I would think that these numbers are W.A.G. (Wild Ass Guess) at
best. Microsoft both wins new clients and they lose some
clients. Hopefully they win more than they are losing.

I would not bank any research document or monetary business
decision on numbers quoted from this kind of forum without any
basis of reference to check on the data. If you are a Microsoft
partner or ISV...why do you not contact appropriate Microsoft
people themselves?
